Sharon, I would question the assertion that residential greenwaste can not be composted "economically" into a high quality product. We have been doing just that since 1989. We have an ordinance preventing "yard waste" from going in residential garbage cans. It has been very effective in removing this material from the msw stream. The material goes to a compost facility about 30 miles away and the resulting product, Cedar Grove Compost, is sold all over the region. The contracted tip fee at the compost facility for Seattle yard waste is currently about $24 per ton (and they are still in business!).

They both said that residentially-collected material is too contaminated to economically use as a composting feedstock. As a municipal collection agency, this leaves me with limited choices: collect separated greenwaste and take it to the local landfill where it is used as ADC, collect separated greenwaste and take it to the local composter for grinding and use as ADC, spend a large sum of money to take separated greenwaste to a far-away composter who may compost it or may grind it and send it for ADC, collect greenwaste co-mingled with refuse and send it to our waste-to-energy plant. I don't want to get into the justification or lack of same for WTE here, but, given these choices AT THIS POINT IN TIME, my choice as a municipality seems pretty clear. My point is not to try to justify WTE. Instead, I would advocate including ADC in the landfill ban. In other words, greenwaste shouldn't go into a landfill period -- not in the trash cells, and not over them either. Until landfilling greenwaste (in whatever form) is no longer an option (or is economically infeasible), it will be difficult and expensive to do the right thing. And if it's expensive, you can bet that municipalities won't do it -- not with the kinds of budgetary constraints we all operate under these days. Of course, you can't just ban landfilling the material without having some other option in place, but that's another discussion.
